Australodelphis
''Australodelphis mirus'' is an extinct Pliocene dolphin.〔(The Paleobiology Database Australodelphis page )〕 ''A. mirus'' is known from fossils found in the Sørsdal Formation, Mule Peninsula, Vestfold Hills, East Antarctica. The genus has been described as an example of convergent evolution with beaked whales.〔
==Name history==
The generic name ''Australodelphis'' is derived from the Latin ''australis'' meaning southern and ''delphis'' meaning dolphin, in reference to its discovery in Antarctica. The species name ''mirus'' is Latin for strange or wonderful, and was chosen to reflect the unexpected morphology of the type specimen. While not described until 2002, the type specimen of ''A. mirus'' was collected between 1985 and 1986, and a further four specimens were found between 1986 and 1994.〔 Prior to the description of ''Australodelphis'' in 2002, the genus was mentioned briefly in several publications between 1988 and 1993. The holotype skull was figured in 1988 by R. E. Fordyce and ''Australodelphis mirus'' first appeared as a ''nomen nudum'' in E. H. Colbert's 1991 "Mesozoic and Cainozoic tetrapod fossils from Antarctica".〔 A second species of ''Australodelphis'' was noted by R. E. Fordyce and G. Quilty in their 1993 publication on the stratigraphic context of the Marine Plain sediments, but this second species has yet to be formally described.
